Referringto the accompanying drawings Which'are madea part h'ereof'and on. Which similar reference characters indicate similar parts :-V

Figure 5,v a plan. sho-.Wing Ithe. .relationship ofthe air ventilator to th''rotation of the basket; and

Figure 6, a detail of the supporting bearing of the basket.

In the drawings reference character 10 indicates a base supported by legs 11, this base being connected to an upper member 12 of similar form by means of a side- Wall 13 and by tie-bolts 14 at spaced intervals about the same. The casing thus formed has an outlet 15 adjacent its lower end for escape of fluid. Inside the casing is a centrifugal basket 16, intended in the present embodiment of the invention to lhold articles of textile material such as garments Which have been treated with Huid such as ket being rotated by higi speed, the fluid Will escape by centrifugal action through the holes 17 of which a large number are provided at spaced intervals about the outer Wall of the basket.

Underneath the basket a step bearing 18 is mounted on the disk 10 and a pointed bearing. member 19 on the basket rests in a correspondingly formed recess in the upper face of the step bearing. The upper end of the basket consists of a disk 2O of sheet metal or the like having a depending ange surrounding the body of the basket. A shaft 21 (Fig. 3) is secured to the disk 20 at the center thereof and extends up through a bearing 22 in the disk 12. Above this disk gasoline. The basthe shaft is provided With a friction gear-23 corrnposedzh e.v g. of leather disks held in place by a pair of Kclamping members 24 andf25.` onefof Which is secured*V to the shaft byV a pin 26 andv the other by--a screw 27 engagingv l threads in the upper end of the shaft.

The friction gear 23 isv engaged at one side by a friction g'e'ar.28 on shaft 2.9-having at its other end a crank30 Aby .means of which the machine isy driven. The gear 28 is forced against :gear 23 by means comprising-a roller 31 mountedg'f'or rotation on aplunger 32 by means of a radially movable pin 33, said -rollerV preferably being faced'vv'ith felt. The plunger has a .screW-threaded-portion-34 at its end`,remote from the gear 28 anda nut 35-011 Athe threaded portion; serves to regulate :the tensionof a' spring 36 here shown as a coil spring surrounding the reducedrear port-ion 37'of the plunger-.5 Theplunger is mountedforlongitudinal"movement in a rectangular bearing comprising a-base 38 vsecuredto the disk 12:' and apair of'upwardly extending arms-39.* Atthe side yofthe gear 23V remote from' the lgear 28 'another feltfaced roller 40 is mounted on the bracket 22 by means of a readily removable pin 41, this roller serving to sustain the thrust of the plunger 32. By means of the pins 33 and 41 the rollers 31 and 40 can quickly be replaced When necessary. It should be noted that the shaft 29 is journaled in bearings at the upper ends of arms 39.

A fan casing 42 is supported on the base 10 by means of a bracket-43 and communicates With the interior of the casing 13 by means of a passage 44 so arranged as to direct a blast of air approximately tangentially to the basket and in the direction of rotation of the basket as indicated by the arrow in Figure 5.v This fan is provided for the purpose of Ventilating the basket and the casing and the air from the fan passes through openings in the disk 12, said disk being in the form of a spider having arms 45 and 46 supporting the bearing 22.

The fan in the casing 42 is driven by a shaft 47 carrying a pulley 48. A belt 49 connects the pulley to a pulley 50 on a shaft 51. This shaft is journaled in bearings on a support 52 mounted in any suitable manner on the disk 12 and the shaft is provided at one end with a friction gear 53 engaging a face of the gear 28 and driven thereby to drive the fan.

It Will be obvious to those skilled in the art. that many changes may be made in my device Without departing from the spirit of the invention and therefore l do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Haring' thus falliv described my said invention, what l claim as new and desire to secure by Letters Patent', is:-

l. ln combination with an extractor haring a cage rotatably mounted therein, a gear connected with said cage, a driving disk for said gear, a shaft carrying said disk,

supports in which said shaft is mounted to slide longitudinally, a rod mounted to slide in apertures in said standards in line with the face of said gear, a roller mounted on the end of said rod adjacent the disk, a spring for forcing said roller against said disk, and means connected with said spring for regulating its tension, substantially as set forth.

An extractor ofthe character described comprising a cage mounted to rotate, a friction gear connected therewith, a. friction disk mounted on a driving shaft and adapted to bear against the face of said gear, means for applying pressure to the opposite side of said disk to force it into driving contact with the face of said gear, and means bearing against the opposite side of said gear to support the same against pressure thus exerted, substantially as set forth.

3. An extractor of the character described comprising a casing, a (age mounted to rotate therein`r a friction gear connected with said cage, a friction disk mounted on a driving shaft adapted to contact with said gear for driving the same, means for holding said faces in ldriving contact and supporting the friction gear against the pressure of the disk, and a Ventilating means connected with the casing comprising a blower arranged so that. its blast will impinge against the cage at an angle in the direction of its rotation, subsi ntially as set, forth.

't. An extractor of the character described comprising; a casing, a cage mounted to rotate within said casing, a driving mechanism for rotating said cage, and a rentilating' means comprising a fan arranged so that its blast will impinge against said cage at an angle in the direction of its rotation, substantially as set forth.

An extractor of the character.described comprising a casing. a cage mounted to rotate within said casing, a driving mechanism for rotating said'cage, a Ventilating means comprising an air passage approximately angential to the wall of the cage, and means to force a blast of air through said passage, substantially as set forth. l

ln Witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana this 19th day of June, A. D. nineteen hundred and twenty-five.
